Climate Forcing
ESRL's Global Monitoring Division conducts sustained observations and
research related to global distributions, trends, sources and sinks of
atmospheric constituents that are capable of forcing change in the climate
of the Earth. This research will advance climate projections and provide
scientific policy-relevant, decision support information to enhance
society's ability to plan and respond.

Ozone Depletion
ESRL's Global Monitoring Division conducts research on the depletion
of the global stratospheric ozone layer and Antarctic ozone hole through
global surface-based monitoring of total-column ozone, ultraviolet radiation,
and ozone-depleting gases, including those regulated by the Montreal Protocol.
Continued surveillance is necessary in order to verify the expected
recovery of the ozone layer.

Baseline Air Quality
ESRL's Global Monitoring Division monitors levels of air quality
elements such as tropospheric ozone, carbon monoxide and aerosol
particles in non-source regions which may be affected by long range
transport from distant sources of industrial pollution. This large-scale
transport affects baseline air quality which must be monitored
in order to determine the importance of regional sources that may impact
the environment and public health.

Research Groups
-
Carbon Cycle Greenhouse Gases
CCGG makes measurements of the spatial and temporal distributions of carbon-cycle gases and provides essential constraints to our understanding of the global carbon cycle. -
Halocarbons and other Trace Species
The HATS group quantifies the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases. -
Aerosols
The goals of this program are to characterize means, variability, and trends of climate-forcing properties of different types of aerosols. -
Solar and Infrared Radiation
Activities involve empirical and theoretical research of the Earth's surface radiation budget. -
Ozone and Water Vapor
Research on the nature and causes of the depletion of the stratospheric ozone layer and the role of ozone and water vapor in forcing climate change. -
Observatory Operations
NOAA/ESRL operates staffed atmospheric baseline observatories from which numerous in situ and remote atmospheric and solar measurements are conducted.
